Puzzled as to what just happened... I plugged my car in last night (Telsa Wall Connector 48 AMPs in my garage) as I typically do during the week. My car is set to start charging at 3:30 AM and my in car meter/limit is set to charge to approx. 88% It finishes an hour or so before I leave the house typically. I usually do 80% but yesterday and today have more driving than usual and is cold out so made sure I was past 80 just below 90%. Day before (yesterday's drive) no issues it charged to 88% or so. This morning as I pull into work I looked and saw I have 88 miles of range remaining and have more than that to drive later today. AWD car, by checking the consumption log I see my car started at 50% charge and is now at 29% charge. ( I rarely look at my meter cause with home charging it is really not an issue for non-trip driving) Last night I returned the car to the garage at 30% so somehow my car charged itself overnight from 30 - 50% ??? I double checked the limit/line in the car, it is set to just shy of 90% Checked my phone as I usually get a notification each morning say my car is charged, this morning no notification. We did not lose power overnight or anything weird like that. If the car did not charge at all that would be one thing ; but my car did charge a little bit which just makes it very puzzling and scary??? Any idea what might have happened? Can only come up with maybe the in car voltage was lower than 48 ; if that is it just a setting or something wrong with my house electricity? I have never not had it charge at 48 AMP before at home and never had anything like this happen before. Really screws up my day as I now have to visit a supercharger location at some point on my way home after a couple client meetings today.
